Description of problem:
I had a merge with conflict. I run "git mergetool" (using meld). I solved several problems in several files. Then on one file I decided I want to cancel the merging (of that one file). While meld was running, I switched to waiting terminal and hit Ctrl+C.

After that I received thousands and thousands of lines:

Was the merge successful? [y/n] /usr/libexec/git-core/git-mergetool--lib: line 38: read: read error: 0: Input/output error
hooks/post-koji-build/watch-koji-builds.py seems unchanged.

I had to kill the process.
